I have an ugly (but working) hack for the ICH5 ata_piix driver
to support hot insertion/removal of drives, but I don't know if/when
I'll be pushing it upstream.
Yes it hang permanently there, after this messages i generally reboot
the server.
Yes it not support SATA drive hot insertion/removal, but i have make
the same test on windows. I unplug one disk when i'm logged and the
system don't stop. The drive is removed from the devices list.
If you can give me the patch for testing it... I would give you my
returns about the good/bad functioning in my case.
Okay, Here is a working patch for a very specific variant of ICH5.
If your PCI IDs don't match what the patch is looking for,
then it should have no effect -- you may need to patch the patch
to contain the correct PCI IDs (from lspci -n).

Implement ICH5 chipset handling for drive hot insertion/removal.
This cannot go upstream, as it conflicts with a more generic
polled-hotplug framework that is currently in development.
Hot-inserted drives are automatically detected within a second or two,
and are ready-to-use within 30 seconds or so. This could be even faster,
but the 2.6.18.8 libata implementation of error-handling is what slows
us down here.

This patch was for 2.6.18.8 -- it *might* apply to newer kernels,
but I haven't ported it forward yet.
Cheers
